Motion F10 features a 1.0 x 1.4" Folded Motion Ribbon Tweeter , a 5.5" Midrange and 2 x 5.5" Aluminum Woofer with a Crossover frequency at 280Hz and 3000Hz. On the other hand, the Motion F20 features a 1.0 x 1.4" Folded Motion Ribbon Tweeter , a 5.5" Midrange and 2 x 5.5" Aluminum Woofer with a Crossover frequency at 230Hz and 2600Hz.
Frequency Response
Motion F10 has a frequency range of 38-25k Hz whereas Motion F20 has a frequency range of 35-25k Hz. With a minimum frequency of 35Hz, the Motion F20 can go slightly deeper then the Motion F10's min frequency of 38Hz.
Below graphs depict how these two speakers compare with the max, min and average values of the Min and Max Frequencies of other speakers in the Floor-standing class in our database.

High Frequency
Floor-standing Speakers
None of these speakers achieves full range experience which is commonly agreed as 20Hz-20kHz. In order to achieve lower lows / deeper bass, we recommend you pair these with a subwoofer. Visit our Powered Subwoofers section to find out more about the available options.
Impedance and Sensitivity
Motion F10 and Motion F20 have the same Impedance of 4 ohms and their sensitivity is also same at 92 dB.
One thing to keep in mind that the lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit comared to higher impedance speakers especially at high volume levels, so make sure the amp you pair with the Motion F10 and the Motion F10 can provide this impedance level.

Power Range
Power
range is the range of input power in watts RMS that a loudspeaker is designed to handle. While using an amplifier within this range ensures the nominal performance , inputting a power that is higher than the max wattage can result in a damaged speaker.
Motion F10 can handle a max power of 300 watts RMS from the amp the whereas Motion F10 has a max power handling value of 250 watts RMS , 50 watts less than the Motion F20.
Keep in mind that a higher max power handling value doesn't necessarily make that a louder speaker
compared to a lower max handling speaker. Loudness or the sound level is also impacted by parameters
such as Impedance, sensitivity and system efficiencies.
Input Type and Bi-Amping / Bi-Wiring
Both Motion F10 and Motion F20 features dual binding post speaker terminals for bi-amping or bi-wiring.
MartinLogan Motion F10's Custom 5-way bi-wire tool-less binding posts terminals allows Bi-amping or bi-wiring
MartinLogan Motion F20's Custom 5-way bi-wire tool-less binding posts terminals allows Bi-amping or bi-wiring
Cabinet Type and Port Position
Both Motion F10 and Motion F20 have bottom firing ports.
Physical Specs
Size of a speaker can sometimes become an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare MartinLogan Motion F10's and MartinLogan Motion F20's external dimensions. MartinLogan Motion F10 has external dimensions of 971 x 286 x 336mm ( 38-1/4inch x 11-1/4inch x 13-1/4inch ) whereas MartinLogan Motion F20 has external dimensions of 1127 x 298 x 362mm ( 44-3/4inch x 11-3/4inch x 14-1/4inch ) .
MartinLogan Motion F20 is clearly the larger of the two speakers. Its body is 12mm wider, 156mm taller and 26mm deeper than MartinLogan Motion F10.
Base Surface Area Comparison
Base surface area of a loudspeaker may become a determining factor when the space in your room or desk is limited.
The base surface area of the MartinLogan Motion F10 is approximately 961.0cm2 / 149.0inch2 and base area of the MartinLogan Motion F20 is approximately 1078.8cm2 / 167.2inch2. The Motion F10 requires 11% less surface area than the Motion F20 which gives it a small advantage on placement in tight spaces.
Weight Comparison The weight of a loudspeaker can become an important factor if you need to move and reposition the unit often. Weight of a speaker can also "sometimes" be an indicator of the rigidity of the enclosure and the quality of the internal components used. The MartinLogan Motion F10 weighs 22.90kg / 50.4lbs and the MartinLogan Motion F20 weighs 27.20kg / 59.8lbs. This makes the Motion F20 19% heavier than the Motion F10.
Here is a comparison of how Motion F10 and Motion F20's weights compare with the average, max and min weights in Passive Floor-standing class.
